You can use the preboot execution environment (PXE) to boot a host. Starting with vSphere 6.0, you can PXE boot the ESXi installer from a network interface on hosts with legacy BIOS or using UEFI. ESXi is distributed in an ISO format that is designed to install to flash memory or to a local hard drive. You can extract the files and boot by using PXE. PXE uses Dynamic Host Configuration Protocol (DHCP) and Trivial File Transfer Protocol (TFTP) to boot an operating system over a network. PXE booting requires some network infrastructure and a machine with a PXE-capable network adapter. Most machines that can run ESXi have network adapters that can PXE boot. The Installing ESXi Using PXE technical note explains how you can PXE boot hosts with ESXi.…

The performance parity between bare-metal and virtualised servers is an accepted fact today. But what about the most demanding applications, such as monster virtual machines running databases and transaction processing applications? Experiments in this paper demonstrate that VMware vSphere 6.0 virtual machines run out of the box at 90% of the performance of native systems even for the most demanding workloads at the highest throughput levels.

Large advances have been made in hardware and every level of the software stack since the virtualized Hadoop tests published in April 2013. This paper shows how to take advantage of these advances to achieve maximum performance. The cluster size remains at 32 two-processor 2U hosts; however, the processor, memory, network, and storage capabilities are all roughly doubled from those reported in the earlier paper. The performance of native and several VMware vSphere® 6 virtualized configurations were compared using the same TeraSort application suite as before. It was found that the more powerful hosts give a larger advantage to multi-VM per host configurations: virtualized TeraSort is now up to 12% faster than the optimized native configuration. The apples-to-apples case of a single virtual machine per host again shows performance close…
